ISO Page Yields

Use of International Industry Standards

Many original equipment manufacturers of printers and multifunction products (MFPs), including Lexmark, utilize the international industry standards for page yields (ISO/IEC 19752, 19798, and 24711).These standards prescribe certain page coverage, printer settings, and test conditions for declaring print cartridge yields. Although declared yields are useful to compare different brands of printers, customers are not likely to use printers in exactly the manner prescribed for these tests. As a result, the actual page yields that customers experience may vary considerably from the manufacturers’ declared yields.

Toner Cartridge Declared Yield vs. Actual Page Yield

Here are some of the leading factors that can impact affect actual page yield performance in laser printers and MFPs:

Not all of the toner that is in a laser printer print cartridge is applied to the printed page. Here are some of the other ways in which toner is used:

• Start up and calibration processes that prepare the printer to print
• Maintenance requirements when not printing
• Some toner will remain in the cartridge when it can no longer be used.

The yield testing process defined by ISO/IEC is likely to experience a lower amount of non-print toner usage than actual day-to-day customer printing.

In many settings, color toner is used to create a richer black. Customers can avoid this feature by changing the printer setting to print or copy only in black.
